目前的研究批判性地评估了非痴呆老年人的认知功能和步态之间的关系。在单任务和双任务条件下评估步态（速度、节奏和步长变异系数）的定量测量。三个认知因素涵盖了执行注意力、言语智商和记忆力。线性回归分析表明，在两种步行条件下，执行注意力都与速度有关。然而，记忆力和语言智商也与速度有关。在两种步行条件下，记忆力都与步频有关。执行注意力与两种步行条件下步长的变异系数有关。线性混合效应模型表明，双任务成本最大的速度，其次是节奏和步长的变异系数。认知功能和步态之间的关系部分取决于所使用的分析方法、评估的步态参数和行走条件。
The current study critically assessed the relationship between cognitive functions and gait in nondemented older adults. Quantitative measures of gait (velocity, cadence, and a coefficient of variance in stride length) were assessed in single and dual-task conditions. Three cognitive factors captured the domains of Executive Attention, Verbal IQ, and Memory. Linear regressions showed that Executive Attention was related to velocity in both walking conditions. However, Memory and Verbal IQ were also related to velocity. Memory was related to Cadence in both walking conditions. Executive Attention was related to the coefficient of variance in stride length in both walking conditions. Linear mixed effects models showed that dual-task costs were largest in velocity followed by cadence and the coefficient of variance in stride length. The relationship between cognitive functions and gait depends, in part, on the analytic approach used, gait parameters assessed, and walking condition.
